Résumé:

We report the possibility to realize complete thermal stabilization of the lasing wavelength lambda(opt) in an all-epitaxial tilted cavity semiconductor laser, wherein the lasing wavelength is governed by the maximum resonance transparency of a lossy waveguide. When the positive temperature coefficient of the refractive index dn/dT is a non-linear function of the alloy composition, which is the case in most semiconductor alloys, there exists the possibility to achieve ultimate control of the resonance transparency wavelength. The thermal shift d lambda(opt)/dT can be positive, zero, or negative. An absolute thermal stabilization of the lasing wavelength is unique as compared to any conventional type of lasers.
